IMPROVEMENT IN MACHINES FOR SWAGING HORSE'SHOES.

Specification forming part of Letters Patent No. 222,8!8, dated December 23,1879; application filed February 3, 1879.

To all whom it may concern:

Be it known that we, DAVID J. FARMER and SAMUEL FARMER, both of Penn Yan, in the county of Yates and State of New York, have invented certain new and useful Improvements in Machines for Swaging Horseshoes, of which the following is a specification.

The subject of our invention is a machine for imparting the final form and finish to horseshoes which have been bent and brought approximately to shape by a preliminary process.

To this end we construct a machine with a drop hammer provided with a gravitatin g pawl, which admits of the hammer being raised by means of an arm projecting from an oscillating shaft, and with a pair ofjaws moving horizontally to compress the shoe on a central former, to which a vertical sliding movement is subsequently imparted by a foot-lever to Withdraw it from the finished shoe and discharge the latter.

In order that our invention may be fully understood, we will proceed to describe it with reference to the accompanying drawings, in WlJlGh-- Figure 1 is a rear view of the machine. Fig. 2 is a vertical section on the line 2 2, Fig. 1. Fig. 3 is a plan of the bed with the upper parts removed.

B is the bed or base of the machine, on which is mounted a shaft, A, carrying cams G U, which actuate levers D D so as to impart horizontal motion to the slides E E, which constitute jawsto compress the shoe on the central former, F. The shaft A has also keyed upon it a crank-wheel, G, to the wrist of which is attached a pitman, H, connected at its upper end with an arm, I, projecting from a shaft, J, to which an oscillating motion is thus imparted.

A horizontal arm, K, projects forward from the central part of the shaft J, to raise the drop-hammer L by engaging with a gravitating pawl, M, depending from the rear side of the cross-head of said hammer, and pivoted thereto in such a manner as to move freely out of the way of the oscillating arm K as the latter moves down, but catch it as it rises, in order to lift the hammer.

A stop, N on the front of the pawl M, by contact with tlie hammer-stock, limits the backward movement of the pawl, so that. the arm K will slip from the face of the pawl and thus permit the hammer to drop.

The motion of the hammer is arrested at the will of the operator by a dog, 0, projecting from a shaft, P, operated by a hand-lever, Q.

The operation of the machine will be clearly understood from the foregoing. description of the parts.

When the shoe is finished the former is drawn down within the bed B by means of a foot lever, B, so as to release the shoe.

Having thus described our-invention, the following is what we claim as new therein and desire to secure by Letters Patent:

1. A horseshoe-swaging machine constructed with a vertically-sliding former, a pair of 'aws oierated b levers for com )ressin the J .8

shoe around said former, a cam-shaft actuating the levers and compressingjaws, and a footlever for withdrawing the former to release the finished shoe, as hereinbefore described.

2. In combination with the aforesaid former, horizontal sliding jaws, actuating-levers, and cam-shaft, the rock-shaft J, arms I K, drophammer L, and gravitating pawl M, provided with a stop, N, substantially as and for the purposes set forth.
